Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672112, here are decompositions:

11 + 8672101 = 8672112
13 + 8672099 = 8672112
109 + 8672003 = 8672112
131 + 8671981 = 8672112
193 + 8671919 = 8672112
373 + 8671739 = 8672112
401 + 8671711 = 8672112
443 + 8671669 = 8672112

Showing the first eight; more decompositions exist.
